Automatic Air Inflation in Vehicle Tyre. This can be placed in
all automobiles while long drives and that can be utilized
while climbing up hills or down hills. It is very necessary for
every automobile to be cautious while driving through long
distances. So, we have fabricated this machine to fill the air
automatically by using control units. Main aim of this project
is that when the air is decreased to the automobile vehicles
then the sensor signal alert the person for usage of air tank
to fill the air in the tyre. Then the air pressure will get
increased in the tyre of the vehicle it is same as the process
of indicating the sensor signal through the person using
solenoid valve to reduce the excess air in the tyre.

ensuring consistent and proper tyre inflation
2. LITERATURE REVIEW
Today automobile sector plays a big role in the economics
of all the countries in the world and lots of researches have
been carried out to improve the efficiency of the vehicle one
the techniques to improve the efficiency of an automobile is
inflate the tyre regularly. As its well-known, one of the most
serious problem that the large motor vehicle has whether
they are for the transportation of passenger or cargo and
especially those used for middle or longer distance travel,
resides the ensuring the correct performance of the tyres.
This means making sure that tyre are inflated and stay
inflated for the right amount of pressure for the load being
carried and for road condition this way one can ensure not
only the preservation of outer covering of the tyres, but also
the correct operation of vehicle without any risks.

1. INTRODUCTION
This paper titled as Automatic Air Inflation in Vehicle Tyre
deals with the difficulty in driving the vehicles with low and
high tyre pressure. The irregular and uneven tyre pressure
causes difficulty in driving and even leads to the accidents.
The project mainly concentrates on maintaining the tyre
pressures and thereby reducing the driving difficulties.
This is done by mechanical means. The air can be inflated
into the tyres without stopping the vehicle. The air from the
air tank is used for inflating the tyres. The air from the tank
is sent to the tyres through a one-way valve. The twist
made in the air hose is prevented by a joint. The design of
the system is very simple and also very economical.
Therefore, it can be implemented easily in the vehicles. The
space requirement for the installation is also very less.
Automatic Air inflation systems in Vehicle Tyre can save
tyre maintenance costs and improve fuel economy by
nearly 1 percent, saving 100 gallons of fuel and eliminating
1 metric ton of greenhouse gas emissions per year.
Properly inflated tyres also have fewer punctures and a
longer life expectancy.
V. Jeeva Bharathi and it’s all (2017) has concluded that
Automatic pressure controlling and self-inflating system
would be exploding as new product in the automobile
supplier industry as such a product does not currently
installed for majority of passenger automobiles, hence the
market conditions would be favorable to release such a
system. It satisfies the user requirement by maintaining ideal
Tyre pressure for under inflated Tyre, also improves fuel
efficiency and overall safety of automobile is concerned. It
assists in monitoring appropriate Tyre pressure constantly,
reduces or increases the Tyre pressure according to
requirement of the Tyre and help in gaining best mileage and
most importantly assures to provide comfortable and safe
driving. The installation of such a system in vehicles is a low
cost affair so all the passenger vehicle can take the advantage
of this very essential system at affordable installation budget

The deflation is a process of letting air or gas out of the
tyres. Deflation is the problem of an automobile vehicle.
Because a certain period of time in air reduced to the vehicle
for running time. So, a long distance travelled vehicle scar
able things for deflation. The air is also decreasing the tyre.
Fleet tyre managers typically ask how frequently they should
be checking tyre pressure and loss so much of air during the
course of the year. Osmosis of air through the tyre casing can
lead to a loss 1to 3 PSI per month, depending on the specific
tyre make and model. The type of compounds used in the
Automatic Air inflation systems monitor and continuously
adjust the level of pressurized air in tyre, maintaining proper
tyre inflation automatically even while the truck is in motion.
Our system uses the vehicles own air-brake compressor to
supply air to all the tyre. Once Automatic Air Inflation system
is installed in Vehicle; it should not require any special
attention from the drivers. This eliminates the need to check

manufacture of the tyre can have a big impact on osmosis.
The composition and gauge of the tyre inner liner compound
also plays significance in osmosis.[2].
4. COMPONENTS AND SPECIFICATION
Inderjeet Singh & it’s all (2016) has concluded that the
tyre implementation system is based on the idea to maintain
uniform tyre pressure of an automobile reduce tyre wear,
increase fuel efficiency & increase overall safety. So, this
system maintains the proper air pressure in tyre. [3].
A pressure sensor usually acts as a transducer; it
generates a signal as a function of the pressure imposed. For
the purposes of this article, such a signal is electrical.
Pressure sensors are used for control and monitoring in
thousands of everyday applications. Pressure sensors can
also be used to indirectly measure other variables such as
fluid/gas flow, speed, water level, and altitude.
4.1 Pressure Sensor
Kamlesh R. Patil has concluded that Tyre Inflation
Systems have several benefits for the transportation industry
and for the for the vehicle owners. These benefits include,
improved vehicle mobility due to improved traction,
improved ride quality and cargo safety due to the reduction
in vehicle vibrations when the correct tyre pressure is used,
reduction in road maintenance, increased fuel efficiency and
a considerable increase in the tyre life of vehicles. Thus, Tyre
Inflation System should be used in vehicles for the
betterment of automobile industry, vehicle owners,
passengers and society as a whole [4].
4.2 ATMEGA16 Controller
3. WORKING PRINCIPLE
ATmega16 is an 8-bit high performance microcontroller of
Atmel’s Mega AVR family with low power consumption.
Atmega16 is based on enhanced RISC (Reduced Instruction
Set Computing) architecture with 131 powerful instructions.
Most of the instructions execute in one machine cycle.
Atmega16 can work on a maximum frequency of
16MHz.ATmega16 has 16 KB programmable flash memory,
static RAM of 1 KB and EEPROM of 512 Bytes.
4.3 LCD (Liquid-Crystal Display)
A liquid-crystal display (LCD) is a flat-panel display or other
electronically modulated optical device that uses the lightmodulating properties of liquid crystals. Liquid crystals do
not emit light directly, instead using a backlight or reflector
to produce images in color or monochrome. LCDs are
available to display arbitrary images (as in a generalpurpose computer display) or fixed images with low
information content, which can be displayed or hidden, such
as preset words, digits, and 7-segment displays, as in a
digital clock. They use the same basic technology, except that
arbitrary images are made up of a large number of small
pixels, while other displays have larger elements.
Fig -1: Block Diagram of System
It consists of solenoid valve, control unit, pressure
sensor and Tyre model. Here we are using pressure sensor to
detect the pressure level in the tyre. The level of pressure is
already programmed in the control unit. When the pressure
level is decreased, the sensor gives signal to the control unit.
After that the controller unit will open the solenoid valve for
filling the air when the required pressure is obtained the
control unit will turn OFF the solenoid valve. In case the
pressure level will be more than the required level means
control unit will switch ON another solenoid valve for air to
the atmosphere. When the required pressure is reached the
operation will be stopped by the control unit.

4.4 Relay Switch
A relay is an electrically operated switch. Many relays use an
electromagnet to mechanically operate a switch, but other
operating principles are also used, such as solid-state relays.
Relays are used where it is necessary to control a circuit by a
separate low-power signal, or where several circuits must be
controlled by one signal.

4.7 Air Compressor
An air compressor is a device that converts power (using an
electric motor, diesel or gasoline engine, etc.) into potential
energy stored in pressurized air (i.e., compressed air). By
one of several methods, an air compressor forces more and
more air into a storage tank, increasing the pressure.
4.5 Solenoid Valve
It is an electromechanical controlled device which is used to
allow or restricted the flow of air to pass through them from
the compressor. It is attached between the compressor and
the Flexible air hose. The coil\solenoid casing which is
hollow and has a metallic finish in outer, in the hollow part
the coil winding is present, which is energized and deenergized by the lead wire. The plunger is present at the
centre of the casing with the calibrated spring, which is
above the plunger.
4.8 Power Supply
In power supply, power means energy (electrical) and
supply means transportation. It is a device which supplies
the electric power to an electrical load. Its main function is to
convert the electrical current from source to required
current, voltage and frequency to the load.
4.6 Pneumatic Actuator
A Pneumatic Actuator mainly consists of a piston or a
diaphragm which develops the motive power. It keeps the
air in the upper portion of the cylinder, allowing air pressure
to force the diaphragm or piston to move the valve stem or
rotate the valve control element. Valves require little
pressure to operate and usually double or triple the input
force. The larger the size of the piston, the larger the output
pressure can be.

5. ADVANTAGES AND SAVINGS


Under low pressure friction creates heat and if
enough heat is generated the rubber that holds the
tyre cords melts and tyre trails. Because of the extra
resistance an under inflated tyre has when it rolls,
the car’s engine has to work harder. As it effects
mileage it can cause severe loss in the cost
considerations.
It does not only extend tyre life but truck fleets can
also see additional savings from reducing the risk of
expensive tyre failure caused by underinflation.
Installing this system on a trucks drive axles and
trailer costs up to 60000.

For a typical long-haul combination truck, annual
fuel savings could be 28000 in fuel cost and
eliminating 1 metric ton of greenhouse gas
emissions.

Annual tyre maintenance costs can also decrease.

The cost of installing this system in a long-haul
truck is generally recouped in just over 2 years
through fuel and maintenance cost savings.

6. RESULTS AND CONCLUSION
We applied all these techniques to reduce the process time
and human efforts of the conventional manual air filling
system. The system helps to reduce cost and friction
between surface of tyre and road so that will reduce the
wastage of tyre material. As a result, it will increase the life
of tyre. This can be used in all automobile vehicles. Existing
project is designed for ideal condition tyre. In this system we
have developed the next level of running condition of tyre
when tyre is running at 30 to 40 rpm. Because of the vehicles
in a running condition can sometimes causes puncturing the
tyre. So, the alternative sensors are used to their process.
Then the air will be filled in the tyre pressure per the
seconds. Then calculate the air filling efficiency and find out
the punctured tyre. So easily identified the punctured and to
solve the problems. This process is an advanced technique of
our project.
